Computational Kinetics Simulation of the Dissolution and Coarsening in the HAZ during Laser Welding of 6061-T6 Al-alloy
TL;DR: In this article, the microstructural evolution in the HAZ of laser beam welding of aluminum alloys is modeled using the computational thermodynamics and kinetics software DICTRA and the volume fraction and average precipitate size were calculated for several types of weld thermal cycles, under extremely non-isothermal conditions.
Journal ArticleDOI
Life Cycle Assessment of an Oscillating Wave Surge Energy Converter
Maria Apolonia,Teresa Simas +1 more
TL;DR: In this article, the authors presented a preliminary Life Cycle Assessment (LCA) of the MegaRoller wave energy converter, aiming to contribute to decision making regarding the least carbon and energy-intensive design choices.

Superelasticity Preservation in Dissimilar Joint of NiTi Shape Memory Alloy to Biomedical PtIr
A. Shamsolhodaei,João Pedro Oliveira,B. Panton,Belén Ballesteros,Norbert Schell,Y. Norman Zhou +5 more
TL;DR: In this paper, a laser microwelding was used to join superelastic NiTi to biomedical PtIr, which can be used in multicomponent biomedical devices, and the NiTiPt phase inside the fusion zone had a strong metallurgical bonding with NiTi base material due to the smooth transition of its grain orientation towards B2 NiTi.
Journal ArticleDOI
Multi-scale Simulation for the Columnar to Equiaxed Transition in the Weld Pool
TL;DR: In this article, the columnar to equiaxed transition (CET) in the weld is used to refine the grain structure and improve the mechanical properties of the weld.
Journal ArticleDOI
Effect of solution annealing on weldability of aged alloy 800/25Cr–35Ni steel dissimilar welds
TL;DR: In this paper, the effects of a preweld solution annealing, heat input, interpass temperature and type of filler metal on the weldability of two alloys were investigated.

A review on selective laser sintering/melting (SLS/SLM) of aluminium alloy powders: Processing, microstructure, and properties
TL;DR: In this article, the state of the art in selective laser sintering/melting (SLS/SLM) processing of aluminium powders is reviewed from different perspectives, including powder metallurgy (P/M), pulsed electric current (PECS), and laser welding of aluminium alloys.
Journal ArticleDOI
Dislocation network in additive manufactured steel breaks strength–ductility trade-off
Leifeng Liu,Qingqing Ding,Yuan Zhong,Ji Zou,Jing Wu,Yu-Lung Chiu,Jixue Li,Ze Zhang,Qian Yu,Zhijian Shen +9 more
TL;DR: In this article, the authors show that the pre-existing dislocation network, which maintains its configuration during the entire plastic deformation, is an ideal modulator that is able to slow down but not entirely block the dislocation motion.
Journal ArticleDOI
Critical review of automotive steels spot welding: process, structure and properties
TL;DR: In this article, the fundamental understanding of structure-properties relationship in automotive steels resistance spot welds is discussed. And a brief review of friction stir spot welding, as an alternative to RSW, is also included.
Journal ArticleDOI
Revisiting fundamental welding concepts to improve additive manufacturing: From theory to practice
TL;DR: In this article, a unified equation to compute the energy density is proposed to compare works performed with distinct equipment and experimental conditions, covering the major process parameters: power, travel speed, heat source dimension, hatch distance, deposited layer thickness and material grain size.
Journal ArticleDOI
Using deep neural network with small dataset to predict material defects
TL;DR: This study attempted to predict solidification defects by DNN regression with a small dataset that contains 487 data points and found that a pre-trained and fine-tuned DNN shows better generalization performance over shallow neural network, support vector machine, and DNN trained by conventional methods.
